Volume ray casting, sometimes called volumetric ray casting, volumetric ray tracing, or volume ray marching, is an image-based volume rendering technique. It computes 2D images from 3D volumetric data sets. Volume ray casting, which processes volume data, must not be mistaken with ray casting, which processes surface data.

Famous quotes containing the words volume, ray and/or casting:
“Measured by any standard known to science—by horse-power, calories, volts, mass in any shape,—the tension and vibration and volume and so-called progression of society were full a thousand times greater in 1900 than in 1800;Mthe force had doubled ten times over, and the speed, when measured by electrical standards as in telegraphy, approached infinity, and had annihilated both space and time. No law of material movement applied to it.”
—Henry Brooks Adams (1838–1918)
“Our reason may prove what it will: our reason is only a feeble ray that has issued from Nature.”
—Maurice Maeterlinck (1862–1949)
“This I do know and can say to you: Our country is in more danger now than at any time since the Declaration of Independence. We don’t dare follow the Lindberghs, Wheelers and Nyes, casting suspicion, sowing discord around the leadership of Franklin D. Roosevelt. We don’t want revolution among ourselves.”
—Lyndon Baines Johnson (1908–1973)
